Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Cleaning Across Bothell
Air duct cleaning in Bothell typically costs between $350 and $650 for a full single-family system, depending on the home’s square footage, number of returns, and the condition of the flex-duct runs. Most jobs are completed in 4 to 6 hours, and you’ll know the exact price in writing before any work begins. Our crews know Bothell’s housing stock intimately – from 1990s two-story production homes near Canyon Park to older ranch-style houses along the Sammamish River corridor. If you’re noticing dust on every flat surface, a musty smell when the furnace kicks on, or rooms that never hold temperature, call (980) 447-2498 and we’ll talk through what’s actually going on in your ducts.
Why Linden Air Duct Cleaning Is Bothell’s Preferred Air Duct Cleaning Company
Homeowners in Bothell call us because we tell them exactly who’s coming to the door before the visit. Every technician’s name and photo arrives ahead of the appointment, and a photo ID badge is shown at the door – every single time. That’s the Threshold Standard, and it matters when you’re home alone with kids or just cautious about strangers in your house. Marcus Veale leads our team with a simple rule: if we can’t verify the person and stand behind the work in writing, we don’t do the job.
We’ve served homeowners here since 2004 as part of the Threshold Group family. That’s two decades of seeing the same flex-duct failures, the same condensation problems, the same post-storm damage patterns. We’re not guessing at Bothell’s quirks. We’ve documented them in thousands of homes. And because we carry Rotobrush and Nikro agitation equipment calibrated for flexible plastic ductwork, we’re equipped for what Bothell homes actually have – not just what a generic cleaning crew shows up with. Written pricing comes before work begins. The 365-Day Done Right Promise means if the work isn’t right, we make it right. Both are in writing, on every job.
Commercial Air Duct Cleaning in Bothell
Commercial Air Duct Cleaning in Bothell serves the offices, clinics, and light manufacturing tenants throughout the Canyon Park tech corridor and downtown Bothell commercial district. These spaces run HVAC systems far longer each day than any home – often 12 to 16 hours – which means enormous volumes of air move through return plenums, mixing boxes, and long runs of flexible and rigid duct. Debris loads build faster. Filters load up. Condensation in Bothell’s damp valley air settles inside poorly insulated sections. A commercial cleaning here involves negative-pressure extraction at the air handler, HEPA-filtered vacuum capture, and agitation of the interior walls with Rotobrush equipment to dislodge impacted particulate. We also inspect for the same boot-separation failures we see in residential North Creek, because some of those commercial parks sit on the same former wetland fill.
In practice, a Canyon Park office suite of 8,000 to 15,000 square feet runs between $1,200 and $3,500 depending on duct length, access points, and the number of rooftop units. We photograph everything, before and after. Maintenance supervisors and property managers get a written report showing the sections cleaned, the pressure readings, and any disconnected runs or collapsed flex we found. The price is in writing before the project starts – no change orders after the fact.
Supply and Return Duct Cleaning
Commercial and residential systems both push air through supply ducts and pull it back through return ducts. In Bothell’s older commercial spaces, the return side often carries the heaviest load: decades of dust, construction debris, and sometimes standing water after a roof leak. We clean both sides under negative pressure, not just the registers.
Video Inspection for Commercial Systems
Before we touch a long commercial run, we push a camera through it. It shows us collapsed flex, standing water, disconnected boots, or contamination that cleaning won’t fix. That footage goes to you. If replacement is the honest answer, you’ll see exactly why.
Air Duct Cleaning Services in Bothell
Air Duct Cleaning Services in Bothell begin with an honest look at what your system actually needs. Most Bothell homes were built in the 1990s and early 2000s with flexible plastic ductwork – not rigid sheet metal. That material sags between joists, accumulates debris in the low points, and traps moisture when the home’s humidity runs high. Our full system cleaning pulls every register, seals the supply side, and runs negative-pressure extraction through the entire network while agitating the interior surfaces with Rotobrush and Nikro equipment. That’s the difference between source removal and a cheap register vacuuming. The price in Bothell for a standard single-family home runs $350 to $650; two-story homes with two air handlers or long crawlspace runs sit at the higher end.
Full System Cleaning
This covers every supply run, every return, the boots, the plenums, and the air handler cabinet. We don’t do per-vent pricing – it’s one flat price per system, agreed in writing before the equipment comes off the van.
Video Inspection
After cleaning, we run a camera through representative runs to show you what’s actually been removed. You’ll see the before-and-after footage of your own ducts, not stock photos. If we find a boot separated at the joist or collapsed flex that cleaning won’t resolve, we show you that footage and talk through repair options.

Trusted Brands We Service in Bothell
We run Rotobrush and Nikro agitation and extraction equipment because Bothell’s flex-duct-heavy homes need contact cleaning – not just suction at the register. On the air-quality side, we work with products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If you’re adding filtration or a dehumidifier to address Bothell’s damp-valley indoor humidity, we’ll spec a system sized to your actual duct configuration, then install it properly sealed. We don’t stock parts for every brand, but for common Bothell HVAC configurations – especially 1990s Carrier, Trane, and Lennox split systems feeding flex runs – we carry the boots, collars, mastic, and filter media needed to make repairs during the same visit. That saves you a second trip and a second invoice.
Common Air Duct Cleaning Problems We See in Bothell Homes
- Flex-duct boots pulled away from registers. In the North Creek subdivision belt especially, 30 years of thermal cycling plus settling on former wetland fill has separated boots from ceiling joists. The run blows conditioned air into the crawlspace instead of the room.
- Condensation and biofilm inside under-insulated flex ducts. Bothell’s low valley position and 50+ inches of annual rain keep indoor humidity high. Moisture condenses inside poorly insulated runs, and mold colonies form where drier Eastside cities like Redmond rarely see the problem.
- Second-floor bedrooms that never hold temperature. Usually a disconnected or collapsed run above the ceiling, not an undersized furnace. The fix is mechanical – reattach, replace, or seal – not another thermostat adjustment.
- Heavy pollen and spore loads from surrounding second-growth forest. Alder and cottonwood along the Sammamish River, plus Douglas fir on the hillsides, pump particulate into homes every spring and fall. Ducts that haven’t been cleaned in a decade carry that load into the living space all year.
Pricing for Air Duct Cleaning in Bothell, WA
A full residential system cleaning in Bothell runs $350 to $650 for a single-family home with one air handler. Homes with two systems, long crawlspace runs, or significant debris accumulation sit at $500 to $850. Commercial duct cleaning in the Canyon Park corridor runs $1,200 to $3,500 depending on square footage and access. These are written, flat-rate prices agreed before work begins. No per-vent pricing, no surprise line items when the tech walks the system. The variables that actually affect your price: number of returns, total run length, and whether we find disconnected boots or collapsed sections that need repair. Call (980) 447-2498 for a free estimate – you’ll get a specific number, not a vague “it depends.”
If your system has water intrusion from a storm or flood, the honest answer may be replacement rather than cleaning. We document the difference with camera footage and moisture readings. More on that below.

FAQs About Air Duct Cleaning in Bothell
It depends on what the water touched and for how long. Flex-duct with an internal fiberglass liner that sat wet for more than 48 hours usually cannot be cleaned back to a safe condition – the liner absorbs moisture and holds it against the insulation, and mold colonizes inside the material itself. Rigid sheet metal can often be cleaned and disinfected if the water was clean and the exposure was short. We camera every wetted run and take moisture readings before recommending anything. You’ll see the footage. If replacement is the honest answer, we tell you that and document why in writing. Call (980) 447-2498 to schedule an inspection.
Because it often is. The original flex-duct boots in many North Creek homes have pulled away from the ceiling joists after 30 years of thermal cycling and settling on former wetland fill. The disconnected run dumps conditioned air into the crawlspace and draws damp, cool valley air back through the gap. We fix it by reattaching and sealing the boot, then remeasuring the run under negative pressure. It’s a mechanical failure, not an HVAC sizing problem. Call (980) 447-2498 for a camera inspection.
Bothell sits in a low valley where cold air and moisture pool. With 50-plus inches of annual rain and high indoor humidity for much of the year, condensation forms inside under-insulated flex ducts far more readily than in drier, higher terrain like Redmond or Bellevue. That standing moisture feeds mold and biofilm growth inside the duct liner. A cleaning that doesn’t address the underlying condensation – or doesn’t dry the system properly – gets re-contaminated within a season. We check insulation integrity and humidity as part of the job. Call (980) 447-2498 if you smell mustiness when the system runs.
Most insurers require documentation that clearly shows what happened, what was damaged, and why cleaning is or isn’t sufficient. That means camera footage, moisture readings, and a written assessment from a contractor who can articulate the failure mode. We provide exactly that. For North Creek homes with boot separation and crawlspace discharge, our documentation has supported successful replacement claims because the failure mode – settling on former wetland fill – is specific and verifiable. We’ll give you the evidence your adjuster needs. Call (980) 447-2498 to start the inspection.
Yes. We clean commercial systems throughout Canyon Park, from small office suites to multi-tenant buildings. The job involves negative-pressure extraction at the air handler, HEPA-filtered capture, and interior agitation – plus full camera inspection before and after.
